SWING-JOINT FOR STEAM..

SBECIPICATION forming part of Letters Patent No. 324,874, dated August 25, 1885.

- -Application filed Apt-111615 85. (No model.)

To all whom may concern:

Be it known that I, HORACE J. MORTON, re-

siding at Chicago, in the county of Cook and State of Illinois, and a-citizen of the United 5 States, have invented a new and useful Improvement in Swing-Joints for Steam, 850., of which the following is a full description, reference being had to the accompanying draw ings, in which Figure 1 is a side elevation. Fig. 2 isa' centijal vertical section; Fig. 3, a detail; Fig. 4, i a section at line a: of Fig. 3. Fig. 5'shows the coupling-piece with the ring removed. Fig. 6 shows the divided ring.- Fig. 7 shows on a small scale a perspective of my jo'intwith pipes attached thereto. Fig. 8 is a modification.

My invention relates, primarily, to swing. joints for connecting tubes which are used to convey steam.

The leading objects of my invention are to so construct such a joint that it can swingreadilywithout wear, so that it can be readily.

can be connected to the elbows O D..

packed and be steam-tight without interfering with its easy movement, and so that the obstruction to the passage of steam will be as slight as possible, which I accomplish its illustrated in the drawings, in which- A is a coupling piece, which is screwthreaded at one end, the remaining portion being smooth, except that it is provided with a groove, a, extending around it. j

bis a ring made in two parts, so that the two halves can be inserted in the groove a, as

I g side at one end, and upon the inside at the other end. I

d is packing of hemp or any other suitable material. 1

[ D. is'another elbow, screw-threaded upon the inside, at both ends,as'shown.

shown in Fig. 3, the ring projecting beyond- The parts are put. together by first putting the coupling-piece A into the coupling-nut B, the screw-threaded end of the coupling projecting outside of the nut, as shown in Fig. 2, and the projecting portion of the ring b'resting upon the shoulder 0. Then any suitable packing is to be placed around the smooth part of thecoupling-piec'eand between it and the wall of the coupling-nut B, the packing resting againstthe projecting part of the ring b. Then the elbow D is to be screwed upon the projecting screw-threaded end of the coupling piece A. Then the elbow C is-to be screwed to place, compressing the packing. When-all this has been done, the parts will be substantially as shown-in Figs. 1 and 2. l

The coupling-piece A can be easily rotated, turning in the ring I), producing but very little friction or wear, and the compressed packing 7o"- kl will not interfere with the easy movement of the joint; or the coupling-nut and the ring b can move around the coupling A.

. Pipes through which steam is to be conveyed The'forin and construction of this joint are such that the opening through it can be large without sharp angles, so that there will be but little obstruction to the passage of steam. 1

In Fig. 7'I have shown on a small scale two .pieces of pipe connected to the swing-joint,

and it -is' evident that these pipes may be brought to any desired angle with each other by rotating one or both parts of the swingjoint.

I do not limit myself to the use of this joint in connection with steam-pipes', but it may be used for any other purpose to which it is adapted.

- The divided ring is the only part upon which any material wear can comein use, and if this ring should wear so as to afi'ect the joint it can be very easily replaced.-. 7

'The form which I have shown Iregard as the best; but in Fig. 8 I have shown a modification which may be used in some cases, in which the part f of the coupling-piece is made V smaller than before, so that it can pass through a solid ring -of the same-size as the ring com- 1 posed of two parts, as above described. If this too modification be used, the. solid ring can be" placed inthe coupling-nut, resting on the shoulder e, and then the screw-threaded end of the coupling A can be passed through the ring, the shoulder 9 coming in contact with the ring.

What I claim as new and desire to secure; by L tters Patent, is-

1. In a swing-joint, the combination of the coupling-piece A, a loose ring mounted upon and encircling the same, and a coupling-nut,

1c B, substantially as desci'ibrd.

2. A swing-joint consisting of a couplingpiece, A, provided with a groove, a, in combiuation with a loose ring and a coupling-nut, B, substantially as and 'for the purposes specified'.
